Random
The random
package provides several functions for generating random numbers. It uses a cryptographically strong pseudorandom number generator when possible, but falls back to a weaker random number generator when cryptographically strong randomness is not available (on older browsers or on servers that don't have enough entropy to seed the cryptographically strong generator).
Random.id
Summary:
Return a unique identifier, such as "Jjwjg6gouWLXhMGKW"
, that is
likely to be unique in the whole world.
Arguments:
Source codeName | Type | Description | Required |
---|---|---|---|
n | Number | Optional length of the identifier in characters (defaults to 17) | No |
import { Random } from "meteor/random";
Random.id(
42
);
Random.secret
Summary:
Return a random string of printable characters with 6 bits of
entropy per character. Use Random.secret
for security-critical secrets
that are intended for machine, rather than human, consumption.
Arguments:
Source codeName | Type | Description | Required |
---|---|---|---|
n | Number | Optional length of the secret string (defaults to 43 characters, or 256 bits of entropy) | No |
import { Random } from "meteor/random";
Random.secret(
42
);
Random.choice
Summary:
Return a random element of the given array or string.
Arguments:
Source codeName | Type | Description | Required |
---|---|---|---|
arrayOrString | Array or String | Array or string to choose from | Yes |
import { Random } from "meteor/random";
Random.choice(
[]
);
Random.hexString
Summary:
Return a random string of n
hexadecimal digits.
Arguments:
Source codeName | Type | Description | Required |
---|---|---|---|
n | Number | Length of the string | Yes |
import { Random } from "meteor/random";
Random.hexString(
42
);
